Tracing 13 billion years of history by the light of ancient quasars

Astrophysicists in Australia have shed new light on the state of the universe 13 billion years ago by measuring the density of carbon in the gases surrounding ancient galaxies.

The study, published in Monthly Notices of the Royal Astronomical Society, adds another piece to the puzzle of the history of the universe.

“We found that the fraction of in warm gas increased rapidly about 13 billion years ago, which may be linked to large-scale heating of gas associated with the phenomenon known as the Epoch of Reionization,” says Dr. Rebecca Davies, ASTRO 3D Postdoctoral Research Associate at Swinburne University of Technology, Australia and lead author of the paper describing the discovery.
